Soy milk


Hello: Recently, whenever I drink soy milk, my throat feels very dry all day, and I have a strong urge to cough.
I think I might be coming down with a cold! However, I have never experienced this before, so I would like to ask if there are any diseases or conditions that contraindicate drinking soy milk? Additionally, I often feel a heavy sensation in my forehead accompanied by headaches.
What foods should I avoid? Thank you!!!

Hello! Feeling a dry throat and the urge to cough after drinking soy milk may be due to its high sugar content; you could try reducing the sugar level to see if it improves.
As for frequent headaches, it is advisable to seek medical attention to identify the underlying cause.
Additionally, due to its high phosphorus content, patients with kidney disease should consider their consumption of soy milk carefully.
Best wishes for your health from Dietitian Shih Kuei-Mei, Director of the Nutrition Department at Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Soy milk is a popular alternative to cow's milk, especially for those who are lactose intolerant or prefer plant-based diets. However, like any food product, it can have varying effects on different individuals. In your case, experiencing dryness in your throat and a persistent urge to cough after consuming soy milk may indicate a sensitivity or an allergic reaction to soy. While soy allergies are relatively common, they can manifest in various ways, including respiratory symptoms, digestive issues, or skin reactions.

If you have never experienced these symptoms before, it could be that your body has developed a sensitivity over time, or it could be a temporary reaction due to other factors, such as an impending cold or environmental allergens. It is essential to monitor your symptoms closely. If they persist or worsen, it would be wise to consult a healthcare professional for a thorough evaluation.

In terms of health conditions that might contraindicate soy milk consumption, individuals with soy allergies should avoid it entirely. Additionally, those with certain thyroid conditions, particularly hypothyroidism, may need to be cautious with soy products, as soy can interfere with thyroid hormone production. However, this typically applies to excessive consumption and is not a concern for most people who consume soy in moderation.

Regarding your headaches and the feeling of heaviness in your forehead, it is crucial to consider various factors that could contribute to these symptoms. Dehydration, stress, lack of sleep, or even dietary triggers could be at play. Common dietary triggers for headaches include aged cheeses, processed meats, alcohol, and caffeine. Keeping a food diary to track what you eat and when your headaches occur can help identify potential triggers.

If you suspect that soy milk is contributing to your symptoms, it might be beneficial to eliminate it from your diet temporarily to see if your throat and headache symptoms improve. In the meantime, consider incorporating other sources of calcium and protein into your diet, such as almond milk, oat milk, or dairy alternatives that do not contain soy.

In summary, while soy milk is generally safe for most people, individual reactions can vary. If you experience adverse symptoms, it is essential to listen to your body and consult with a healthcare professional for personalized advice. Additionally, maintaining a balanced diet and staying hydrated can help alleviate headaches and improve overall health.
